In the autumn of 1998, Toyota introduced the first generation of the rear-wheel-drive Altezza sedan, which was marketed in other regions as the Lexus IS 200. It featured an advanced double-wishbone suspension on both axles, delivering a balance of ride comfort and enhanced handling stability. This article provides detailed fuse and relay box diagrams for the first-generation Toyota Altezza / Lexus IS 200 (XE10 chassis; model years 1998–2005).
Below are the location diagrams and photos for the power distribution boxes. The fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
Engine Compartment
The main fuse box is located near the battery, while an auxiliary relay box is positioned further forward (closer to the headlight).
